The murder charge comes after detectives reissued their appeal for anyone with information about the murder to come forward.

It is clear that there is a misguided loyalty where some people are not speaking to the police, protecting those involved.

I would ask those who are reluctant to come forward to do so, so Jamil and his family can get the justice they deserve.

I would also like to reiterate my reassurance to anyone who has witnessed this horrific attack that my officers are here to protect you and will treat any information you have with the utmost sensitivity and discretion.

A 15-year-old boy has been charged with the murder of a teenager stabbed to death in a park. 18-year-old was found slumped in the road near Evans Grove in Feltham in west London following the "horrific attack" last week.

The 15-year-old, who cannot be named due to his age, will appear at Uxbridge Magistrates' Court later this morning. A 15-year-old girl and a 16-year-old boy arrested yesterday on suspicion of murder remain in custody.
